St.Maarten Weather Update July 18th 2010
By Erin Jaworski <erin.jaworski at gmail.com>
Date: Sun, 18 Jul 2010 15:15:49 -0400

Good Afternoon! The island of St.Maarten has been experiencing steady rainfall with scattered thunderstorms all day ( Sunday July 17th 2010 ). This system has been over the island all day, however there is a very low chance of the system turning into a tropical cyclone. The NWS is predicting a 10 percent chance that the Atlantic tropical wave will turn into a tropical cyclone over the next 48 hours. The precipitation and thunderstorms will continue throughout the night with easterly winds picking up in speed. Try and stay dry St.Maarten!

In El Salvador the rains have left at least 1500 people affected, you can see a few pictures of the floods here:
http://www.elsalvador.com/mwedh/nota/popGaleria.asp?idArt=4980934&idcat=6364

By the way, the newspaper says in one of the pictures that a tropical depression is affecting the country but we know that's not true.

And this is the map with the rainfall between 7:00 am yesterday and 7:00 am today, the maximum was 95.7 mm/3.77 inches.
